STMicroelectronics VNLD5300-E

Overview

VNLD5300-E from STMicroelectronics is an AEC-Q100 qualified, fully protected low-side driver IC for automotive resistive and inductive loads, featuring 2 A continuous drain current, 300 mΩ R_DS(on) at 25°C, 41 V overvoltage clamp, thermal shutdown with automatic restart, and SO-8 package. It drives solenoids, relays, and lamps in engine control units and body electronics.

For engineers reviewing the VNLD5300-E datasheet, VNLD5300-E pinout, VNLD5300-E application, or VNLD5300-E equivalent, key selection criteria include its dual-channel low-side switching architecture, integrated diagnostics via open-drain STATUS pins, power limitation under overload, fast demagnetization capability for inductive loads, and compliance with automotive EMC and safety requirements.

Technical Context

The VNLD5300-E integrates two independent VIPower MOSFET channels in a single SO-8 package, each with CMOS-compatible voltage-controlled inputs (IN1/IN2), dedicated DRAIN/SOURCE terminals, and open-drain diagnostic STATUS outputs. Its protection logic implements current limiting (2–3.8 A), thermal cycling (150–200°C shutdown/reset), and overvoltage clamping (41 V typical) without external components.

Switching behavior is characterized by 6 µs typical turn-on delay, 3 µs turn-off delay, and <0.028 mJ turn-on energy at 13 V supply and 16 Ω load. The device supports fast demagnetization of inductive loads and maintains <10 µA standby current while providing ESD protection up to 5 kV (HBM) on all pins.

Key Specifications

Pinout & Package

FAQ

What is the maximum inductive load energy the VNLD5300-E can safely demagnetize?

The VNLD5300-E supports up to 26 mJ single-pulse avalanche energy (E_AS) at 150°C junction temperature. For repetitive demagnetization, Figure 6 in the datasheet specifies maximum turn-off current versus inductance and time-e.g., 10 A into 1 mH for ≤1 ms at T_j,start = 100°C. Exceeding these limits risks thermal shutdown or latch-up.

Can the STATUS pins be directly connected to a 3.3 V microcontroller I/O without level shifting?

Yes-the STATUS pins are open-drain with 0.5 V max low-level output voltage at 1 mA sink current and 10 µA leakage in high state. A 3.3 V pull-up resistor (e.g., 10 kΩ) ensures compatible logic levels; no level shifter is needed. Ensure MCU input hysteresis or software debouncing handles transient noise during fault transitions.

How does the VNLD5300-E handle short-circuit conditions on the DRAIN pin?

Under short-circuit, the device immediately limits output current to 2–3.8 A (I_limH), then reduces to 1.4 A (I_limL) during thermal cycling. If junction temperature reaches 150–200°C, thermal shutdown activates, disabling the channel until temperature drops by ≥7°C. STATUS pin pulls low to signal the fault condition to the host controller.

Is the VNLD5300-E pin-compatible with earlier OMNIFET II devices like VNLD5090?

No-VNLD5300-E uses a different pin assignment: IN1/VSUPPLY1 and IN2/VSUPPLY2 share pins with supply functions, whereas VNLD5090 has separate V_CC and IN pins. The SO-8 footprint is identical, but signal routing and PCB layout must be redesigned to match the updated pinout shown in Figure 3 of DS9083 Rev 9.
